Some crossbows still come with open sights, but you’ll be much better served using a scope. These optical sighting devices make accurate shooting much easier. For magnification, you can choose from just about anything — 1X to 9X. Inside the scope is the reticle, defined as some configuration of horizontal and vertical crosshairs, though for crossbows, it also includes any object projected or suspended across the field of view. Choices begin with a simple, single red dot or crosshair. With them, you sight-in for a fixed distance—typically 20 yards—but you must compensate for longer shots by holding higher. Multi-reticle scopes are the most popular, particularly those with three or four dots or horizontal crosshairs. The top one is sighted in for 20 yards, and the next two are fixed at intervals that will be dead-on at 30, 40 and 50 yards, respectively, on most bows.
If you going to spend a ton of money on a crossbow, don’t skimp on the scope. You need to have a quality scope too. Red dot scopes are the most basic type of scope with no magnification but just the red dot(s). All you need to do is adjust that red dot to lie in the target and then shoot. There is also a wide range of the brightness settings as well. For the places where have enough light, you may not need to adjust these settings. However, on the contrary, a dimmer is rather essential to have the errant sight. Moreover, for those who want to shoot at different ranges, you can choose the scope with many red dots. Each dot is used for a determined range. For those who are new bow-archery and need more practice, this type is the best choice.
A contrast to the red dot ones, an optic scope has the magnification. If the red dot scopes use the dot(s) for one or more ranges, the optic ones use the reticle(s). So, there are two kinds of this type: the single crosshair reticle and the multi-reticle. Also, it provides you the illumination settings to help you get the most accurate sight on the lacking of light condition. For hunters, this type is an awesome scope as the hunting-party usually occurs early in the morning or lately in the afternoon when the light is poor. This type allows the hunters to have the best light transmission by capturing as more as possible the light available.
When choosing a scope for your crossbow, you need to be aware of a couple of terms that will help in the decision making. You always hear about a scope’s magnification. The magnification portion of the scope measures how much better you can see an object through the scope, then with your naked eye. The field of view is the scope’s sight picture at a specific distance. For example, a scope could have a sight picture of 11 feet at 100 yards. Remember that the higher the magnification is, the narrower the field of view is. I hope this will make buying your next crossbow scope easier. With so many great scopes to choose from, it is good to do your homework first.
